Hey there,

I just got home from my vacation, went to put in all my powerplug and check everything,
everything works,
except my DNS, the light on the power adapter doesnt even turn on.
So i called the Support Desk here in the NL.

They nicely said you only have a year warranty on the power supply so if you have it any longer your screwed.

I got it for 1.5 years now so no luck there. But He said you should be able to use a universal adapter.

He didnt give me any brands or models that are possible for use.

Do any of you guys use a universal power adapter for the DNS en can tell me which brand and model.
because the connector on the DNS isnt really universal since its the only device i have with that connector

To bad Dlink doest deal like Lacie, who just sent me a new adapter when it failed after 2.5 years.

Thanks in advance

I don't think you'll find a "universal" adapter to power the DNS-323 - if I'm correct, the power brick has dual voltage output (+5V & +12V).

I'm away from home otherwise I would take a look at mine and get you some more details - depending on your ability with a soldering iron, it's theoretically not too difficult to locate a switch mode power supply from an electronics supply house and wire it up to the existing cable.

Try to repair the PSU yourself.
If you'r lucky only the fuse inside is blown.

Most of the times these PSU's have screws underneath the 4 feet. (See picture attached.)
Remove the feet and screws are visible.

Of course at your own risk, blah blah.
(Be shure to disconnect power cable and discharge the 300V capacitor inside before playing with it.)

Thanks for that picture, perssinaasappel.

The label shows the voltages and current requirements and also which pins in the plug are used to supply which voltages

$29? I would not even turn on the soldering iron.

I would also try on the E-bay.

I agree (assuming that is the right power connector; voltages are correct). Notice the picture for the DNS-323 connector shows only 4 pins while the promax description states a 6 pin connector.

I did a quick look on ebay yesterday and came up empty on just the power adapter. Plenty of offers for the whole DNS-323 product.

So - $29 + 10 minutes with a soldering iron a pair of nippers and some heat shrink tube.

I guess the first step must be open the brick and see if the internal fuse is blown.
This will cost you a lot less if you'r lucky.

IF you're lucky ...

I'm going to bet it's not the fuse - the brick contains a switch mode power supply, and it takes a "catastrophic" internal failure to clear the fuse on one of those.

Here's a quick overview of the front end of a switch mode power supply - your AC line is going to pass through the internal fuse, which is going to be a "slow blow" type, followed by an inductive filter and then a bridge rectifier and filter capacitor - the fuse has to be a "slow blow" type to prevent it from clearing every time power is applied due to the inrush current required to charge the filter capacitor.

If you do open the brick it's fairly easy to verify the front end - just measure the DC voltage on the filter capacitor, it'll be something in the region of 270VDC - just one more reason not to open it if you don't know what you're doing

I got an old adapter from a broken down Lacie hard drive. im gonna switch around the 12v and the 5v cause they are the other way around on the adapter and then gonna use it for the dns.

hopefully it works.

You might want to verify that the adapter for the Lacie can supply the required current - I believe the DNS-323 supply is spec'd for 3A on both 12 & 5 volts, if the Lacie has a lower rating, it may not work - if it has a higher current capacity, it'll work fine.
